【正文】 地區(qū)級客戶管理的系統(tǒng)化、規(guī)范化和自動化，提高企業(yè)的管理效率； （ 3） 該系統(tǒng)本系統(tǒng)特色在于設(shè)計時采用多層架構(gòu)，降低業(yè)務(wù)邏輯與代碼實現(xiàn)之間的耦合性，提高了系統(tǒng)的可擴展性和可維護性，并考慮到訪問的安全性，使本系統(tǒng)具有可擴展、易管理、易維護等特點。 (2) Accordingly, the author attempts to design the software for regionallevel customer management system, which is used by SQL server2020 for the database and based on .NET platform. The system of the multilayer architecture has user information, privileges management, customer information, contract management, sales management and maintenance functions and improves the management efficiency of enterprises。 server cache CLASSNO： 北京交通大學(xué)專業(yè)碩士學(xué)位論文 目錄 vi 目 錄 中文摘要
